So I got the new mold for the 480, they drop at .478 and 392 grains, my .476 sizing die sizes them down to .477ish. So I have loaded and fired about 100 so far. Well I was thinking that I was going to have to send my pistol to a gunsmith to have the cylinder throats opened up and uniformed due to the difficulty of chambering the rounds. Well as it turns out, my problem was too much crimp and it was causing a slight bulge (these Ruger chambers are tight!)which was causing the difficulty. So I have reduced the crimp, they chamber very nice now, and given the amount of case tension on the bullet, I don't see the reduced crimp being an issue, but I dd go ahead and order a Redding profile crimp die as they work really well on my 44 and 454. I don't shoot this pistol as well as my 44 or my 454 from a rest, but it sure shoots great when I shoot offhand, I get 3 to 3 1/2 inch groups from a rest, offhand I have fired groups that are in the 1 1/2 to 2 1/2 inch neighborhood. I am really growing to like this pistol.
